Description

  The present invention relates to a member for repairing a side groove.

  A concrete road side groove (hereinafter referred to as a “side groove body”) having an open upper portion called a U-shaped groove is provided with a concrete lid or a metal lid called grating on the opening portion.

  In particular, a road side groove (side groove body) using a concrete lid is subjected to load and vibration due to the passage of a vehicle, so that the lid body and the upper side of the side groove body are damaged as aged. Therefore, the damaged side groove body needs to be repaired. Conventionally, a method of replacing the entire side groove body or incorporating a resin U-shaped groove inside the side groove body (Patent Document 1) is known.

  However, the above construction method requires a bypass groove for the side groove during the construction period in order to maintain the side groove function, and the construction of the bypass path is complicated.

  Japanese Patent Laying-Open No. 2003-1-1875 (Patent Document 2) discloses means for removing the upper part of the damaged side groove and reconstructing a new part with a mold as a prior art. As a countermeasure, the side groove lid is bonded to the receiving portion of the side groove body with the resin mortar, the upper surface of the lid body and the upper surface of the side groove body are cut, and a sheet material is adhered to the cutting location. Further, a repair method for coating with resin mortar is disclosed.

Further, the installation position of the intermediate portion corresponds to the size of the grating lid 5 and the concrete lid 5b used as the side groove lids used after the repair, and the screw hole 115 It is formed in the place to mount.

  Further, when the repair member of the present invention is used, as shown in FIG. 1, a reinforcing bar 7 is provided in advance so as to be disposed inside the side edge portion 1. The reinforcing bar body 7 is formed by combining a long horizontal reinforcing bar 71 and a vertical reinforcing bar 72 serving as a support leg.

  Next, the side groove repair work using the repair member of the first example (the repair members of the second, third, and fourth examples described later included in the first embodiment are also the same process) It explains along. The construction is performed in the order of an existing object removal process, a member arrangement process, a repair member fixing process, and a finishing process.

  The existing object removing step is performed by removing the concrete cover (which may be a grating lid) 5a to be repaired in the existing side groove (FIG. 7A) and appropriately covering the upper part of the side groove body 6 (the range shorter than the total height of the repair member). ).

  If necessary at the time of excision, the boundary of the road surface in contact with the side groove body 6 may be cut, or an appropriate range of excavation may be performed around the side groove body.

  And the support hole 61 and the attachment hole 62 are dug in the predetermined location of the cut surface of the side groove body 6a which removed the upper part. The support hole 61 has a depth and a diameter at which the headless bolt 116 of the repairing member A can stand upright, and the mounting hole 62 is drilled in correspondence with the vertical reinforcing bar 72 of the reinforcing bar body 7 (FIG. 7B). .

And the said repair member A is arrange | positioned on the excision side groove body 6a. In the above arrangement, the lower portion of the headless bolt 116 is inserted into the support hole 61, and the horizontal position of the repair member A is adjusted by adjusting the screwing position of the headless bolt 116 and the screw hole 115. At this time, the inner surface portion 111 covers the upper part of the inner side surface of the excision side groove body 6a, and the mortar seal portion 113 is brought into contact with the inner side surface of the excision side groove body 6a (FIGS. 6 and 7C).

  In the case where the reinforcing bar 7 has a structure that can stand upright, it is not particularly necessary to dig the mounting hole 62.

  In the repairing member fixing step, mortar (or adhesive or concrete) 8 is injected into the inner side of the side edge portion 1 from the mortar injection hole 124, and the mortar or the like is solidified to fix the headless bolt 116, the reinforcing bar 7, The member A and the excision side groove 6a are integrated.

  The finishing process is to attach the grating lid 5 and the concrete lid 5b to the repair member. In mounting the grating lid 5, the grating lid 5 was placed on the placement surface portion 112, a headless bolt 116 was inserted into the fixing portion of the grating lid 5, and a nut was screwed together, and the grating lid 5 was repaired. It is fixed to the side groove. The concrete lid 5b is also placed on the predetermined placement surface portion 112. Moreover, you may perform the appropriate finishing process of a side groove adjacent road surface as needed.

  Therefore, the renovation of the side groove was completed while maintaining the drainage function while leaving the lower part of the existing side groove body with little damage intact, and the side groove adjacent to the side groove was integrated with the side groove body. Therefore, the durability of the side groove is remarkably improved.

  In particular, as shown in the above-described embodiment, the connecting body portion 2 of the repair member A is constructed between the side edge body portions 1 that face each other at a position corresponding to the size of the grating and the concrete lid serving as the side groove lid. By adopting item 8), the connecting body portion 2 facilitates the mixed mounting of the grating lid and the concrete lid.

  Further, by adopting a configuration (claim 9) in which a screw hole 115 is provided at a predetermined position of the mounting surface portion 112 as a grating mounting position, and a headless bolt 116 is screwed into the screw hole 115 (claim 9). By adjusting the height position of the head bolt 116, it is possible to adjust the horizontal position of the mounting surface of the grating lid 5 and the mounting surface of the concrete lid 5b, and the bolt 116 can also serve as a fixing bolt. is there.

  When only the concrete lid 5b is used after the repair, the headless bolt 116 protruding on the mounting surface that is not required may be cut off before the concrete lid is mounted.

  Furthermore, by adopting a configuration (Claims 11 and 12) in which a flexible mortar seal portion is provided on the back surface of the step portion or a rubber cushion sheet portion is provided on the placement surface portion of the step portion, By causing the inner surface 111 of the stepped portion 11 of the repair member A to follow the inner surface of the side groove 6a, the mortar or the like does not leak when the back surface of the repair member A is filled with mortar or the like. Further, by providing the cushion seat portion 114, it is possible to provide a vibration absorbing function that absorbs vibrations of the grating lid 5 and the like due to vehicle running.

  When the repair member A is formed so as to press the inner peripheral surface of the excision side groove 6a with the inner surface portion 111 of the side edge body portion 1, the mortar seal portion 113 is not necessary.

  The first embodiment of the present invention can adopt the modification shown in FIGS. 3, 4 and 5 in addition to the first embodiment. In the description of each embodiment, the same reference numerals as those in the first embodiment have the same configuration, and the description thereof is omitted.

  Therefore, the repair member D of the fourth embodiment includes a side edge part 1 and a member (not shown) formed in an H shape by linking a connecting part between appropriate positions of the side edge part. It is used in combination and is similar to the case where the repair member is divided and formed, and since it can be formed in a light weight, there is an advantage that handling is easy.

  In the first embodiment, the upper edge forming portion 12 is provided with an elevation surface portion 121, an upper surface portion 122, and a back surface portion 123, and is formed in a U-shaped cross section having a lower opening. The repair member E is formed by forming the upper edge forming portion 12a with an upright portion 121 and an upper surface portion 122a, and in particular, the upper surface portion 122a is narrower than the upper edge width of the side groove body 6a to be repaired. is there.

  Further, a suspension support through-hole 125 used for repair work to be described later is provided on the upper surface portion 122a of the upper edge forming portion 12a.

  Thus, the side groove repair work using the above-described repair member E is an existing method in which the upper portion of the side groove body 6 is cut out in an appropriate range (a range shorter than the total height of the repair member), as in the first embodiment. Object removal is carried out (Fig. 9a, b).

  Then, the repair member E is suspended and supported at a predetermined position above the side groove 6a from which the upper portion is removed by using an appropriate suspension support member b (member arrangement step: FIG. 9C). Of course, in the above-described suspension support, it is needless to say that the inner surface portion 111 covers the upper portion of the inner side surface of the cut-out side groove 6a.

  When the arrangement of the members is completed, a gap c is formed on the outer side of the upper surface portion 122a of the upper edge forming portion 12a so as to communicate the cut and removed space with the ground space (FIG. 9C). The mortar 8 etc. is poured in and the repair member is fixed.

  Therefore, the side groove 6a and the repair member E are integrated by the filling mortar 8 and the side groove is repaired by mounting and mounting the concrete lid 5a or the like on the mounting surface portion 112 of the step portion 11. .
